During his career, Khan won many championship games, received several awards, and held the rank of number 1 in the world for over a decade. During his career, he won 293 out of 331 PSA Professional matches and 99 out of 118 PSA Professional Tour Finals matches. From 1990 until 1996, he remained unbeaten in 81 matches; this was the longest winning streak in top-level professional sports, as recorded by Guinness World Records.^[8][9]

Jansher Khan first came to prominence at 16 when he won the World Junior Squash Championships in Australia in 1986 and then the Senior World Open title in the same year, by beating Australia's Chris Dittmar in the final. At 16, he became the youngest winner in the history of squash by defeating world No.1 Jahangir Khan in the Hong Kong Open. He went on to defeat Jahangir Khan 7 more times that year.Jansher Khan started his career as an employee of the Pakistan Air Force.^{[citation needed]} During his career, he won PSA Professional 293 matches out of a total of 331, PSA Professional Tour Finals 99 out of 118 and from 1990 until 1996 in 81 matches he was unbeaten for a record six years; his longest winning matches streak in top-level professional sports as recorded by Guinness World Records.^[8] His main competitor Jahangir Khan won the PSA Professional 134 matches out of a total of 164, the PSA Professional Tour Finals 61 out of 80 and from 1981 until 1986 in 70 matches he was unbeaten for five years.

Jansher Khan announced his retirement from squash in 2001.^[10] In late 2011, he was diagnosed with Parkinson's disease. In 2020, after suffering from severe back pain while praying and walking, Khan underwent double back surgery successfully at a Shifa International hospital in Islamabad, Pakistan.^[11][8]

Jansher Khan had these words of advice for young players after his successful surgery:

"I would advise today's young players that along with their hard training they must take special care of their back, knee and groin injuries and treat minor ailments timely to avoid serious problems in future."^[8]

In September 2020, at the request of the Chief Minister of Khyber Pakhtunkhwa Mahmood Khan, Jansher Khan joined the Directorate General Sports Khyber Pakhtunkhwa as a head squash coach.^[12]

The facilities available to athletes in Khyber Pakhtunkhwa are unmatched in most other countries. On his appointment, Jansher Khan said, “I will do my best to fill the gap created in the game of squash and make the country a new world champion.”^[2]

Jansher Khan's main squash rival was his Pakistani counterpart, Jahangir Khan. In the 1980s and 1990s, they won most of the 14 World Open titles and 16 British Open titles. From their first match at the Pakistan Open in 1986 to the Spanish Open in March 1991, they played 37 tournament matches. Jansher won 19 of these matches, while Jahangir won 18.^[13]
